DS1233-5+

Supervisors Overview

The DS1233-5+ is a voltage supervisory circuit from the EconoReset series by Analog Devices / Maxim Integrated. It monitors a single input with a threshold voltage of 4.625 V and an overvoltage threshold of 4.75 V. The device features active low, open drain, and push-pull output types. It includes power failure detection but lacks manual reset, watchdog timer, or battery backup switch capabilities. The reset delay time is 350 ms, and accuracy is specified at 5%. Operating supply voltage ranges up to 5.5 V, with a quiescent current of 50 uA. It operates within a temperature range of -40°C to +85°C and is available in SOT-223-4 or TO-92-3 packages.

Supervisors Feature Summary

• Provides power failure detection for system reliability
• Offers flexible output configurations including active low, open drain, and push-pull
• Designed for low power consumption with minimal operating current

Supervisors Applications

• Embedded systems requiring voltage supervision
• Microcontroller reset circuits
• Industrial control equipment monitoring

Supervisors Procurement Notes

Verify component authenticity through authorized distributors. Confirm package type (SOT-223-4 or TO-92-3) matches design requirements. Check RoHS compliance status. Ensure availability aligns with project timelines due to potential limited stock situations.

Supervisors Selection Notes

Select based on required threshold voltage accuracy and output configuration needs. Consider thermal performance within specified operating temperature range. Evaluate space constraints for package selection between surface mount and through-hole options.

Supervisors Part Context

Part of the DS1233 series focusing on simple reset/power-on-reset functions. Designed for cost-sensitive applications requiring reliable voltage monitoring without complex features like watchdog timers or manual resets.

Supervisors Replacement Considerations

DS1233Z-5+ offers similar functionality in SOT-223-4 package. DS1833-5+ provides comparable features in TO-92-3 package. Verify pin compatibility and electrical specifications before substitution.
